Broadway’s best-looking couple — right? — announced they were adding to their family yesterday afternoon, and then shone a spotlight on the growing baby bump last night at a party for new musical “Hair.” Man, Taye Diggs and Idina Menzel are such Broadway babies — I wonder if they gesture to the orchestra after sex?

After making people jealous for 13 years, the couple — who first met while performing in “Rent” — starting talking about having a kid last year. “It’s definitely in the plans,” she told Us. “I’ll settle down and start popping out some babies.”

I wonder what baby names are up for consideration? I would hope that if it’s a boy Jonathan or Larson is on the table since he was the genius behind “Rent.” Otherwise I hear they’re considering Tony, Obie, Lucille and Outer Critics Circle.
